Castle Resources Completes 17 km Tunnel Rehab at Granduc Copper Project

- Tunnel now provides unlimited safe passage for men and equipment into the Granduc Mine

- Rehabilitation sets the stage for underground drilling and development in 2012

TORONTO, ONTARIO -- (Marketwire - Dec. 21, 2011) - Castle Resources Inc. (TSX VENTURE:CRI) ("Castle" or the "Company") is pleased to announce the completion of the rehabilitation of the 17 km long haulage tunnel that connects the Granduc minesite to the haulage road leading directly to year round port facilities in Stewart, B.C.

"This is a milestone achievement in our efforts to move the Granduc Copper project forward," stated Mr. Mike Sylvestre, President, CEO & Director of Castle Resources. "The ability to safely access the mine now clearly positions Castle as an aggressive mine redevelopment story, with the next objective being the rehabilitation of strategic underground levels and exploration drifts for further copper resource definition."

"We would also like to thank Procon Mining and Tunneling's management and crews for a job well done," continued Mr. Sylvestre. "They had a perfect safety record and came in on schedule and on budget, a significant achievement given the length of the tunnel and the fact that it had not been worked in 27 years."

The 17 km long Granduc tunnel was constructed in the mid-1960s by Newmont Mining, the developer and initial operator of the Granduc Mine. It was considered an engineering feat, designed for the fast and efficient rail transportation of ore, people and supplies between the underground mine and the mill.
